How often should my AC be serviced in Medford?

We recommend having your air conditioning system professionally serviced at least once a year, ideally in the spring before the cooling season begins. Regular maintenance extends the life of your AC unit, improves efficiency, and helps prevent costly breakdowns during the hottest days in Medford. Call (978) 293-5770 to schedule your AC tune-up.

When should I replace my AC instead of repairing it?

Consider replacing your AC if it is more than 10–15 years old, requires frequent repairs, uses R-22 refrigerant (which is being phased out), or your energy bills keep climbing. Spencer Home Services provides free estimates on AC replacement in Medford and can help you determine whether repair or replacement is the smarter investment.

How long does AC installation take in Medford?

A standard central AC installation typically takes one day. More complex installations — such as ductless mini split systems with multiple zones or homes that need ductwork modifications — may take 1–2 days. Spencer Home Services handles all permits and inspections required in Medford.

What size AC do I need for my Medford home?

AC sizing depends on your home’s square footage, insulation, window placement, and other factors. An oversized unit short-cycles and wastes energy, while an undersized unit runs constantly without cooling properly. Spencer Home Services performs a Manual J load calculation to recommend the right size AC for your Medford home — ensuring maximum comfort and efficiency.

What’s included in an AC tune-up from Spencer Home Services?

Our comprehensive AC tune-up includes checking refrigerant levels, cleaning condenser and evaporator coils, inspecting electrical connections, testing thermostat calibration, lubricating moving parts, checking drain lines, and verifying system performance. We serve Medford and 60+ nearby communities.

How quickly can a cooling technician get to Medford?

Same-day cooling service is available throughout Medford and the surrounding communities.

Thank you Stephen and Brian and team for helping me get my driveway paved. I appreciate your help with permitting and scheduling.

Adding an update now that I see how badly the light poles are damaged. I specifically told the people who came out to put forms around these lights and they didn’t do so and now look what has happened - more work. Companies should respect the homeowners when they make a specific request like this because there’s a good reason for it because in order to locate the electric electrical, I’m going to have to dig up the new asphalt. This is a real problem and the drainage is a little messed up as well.  Not so happy now.

Update: They sent out an electrician first thing and are going to locate a similar lamp and do the repair. Thanks guys!!! I really appreciate a company that stands by its work!!!!

Spencer Home Services is great. From a very responsive customer call center to a timely technician visit, every step of this stressful process was made easy. Our water heater kicked out on us on a Friday afternoon heading into a Nor'easter weather weekend....ugh....we were up and running with a new system by 5pm. Cannot thank the technicians enough. Shane and Steve were competent, respectful, and efficient. Thank you. Highly, highly recommend Spencer Home Services!!

I needed a sewer line replaced on my property in Lowell. The issue was a complicated one but Will came out to assess the problem and gave me a fair price (much cheaper than another company!). Then the team of Oscar, Bryan, Paul, Julio, Cesar, and others came out and banged out the job in one (long) day. They crushed it. Highly recommend.

We found a 75 year old sewer pipe starting to leak and crack at the joints. Spencer Home Services was extremely helpful in giving an estimate and getting it repaired quickly by a skilled plumber!

I had an excellent experience with Spencer Home Services replacing my main water line — nearly 200 feet long! The crew worked efficiently and managed to finish everything within a single day, which was very impressive.

The pricing was great, and the team went above and beyond with the cleanup and grading afterward — the yard looked neat and well-restored when they were done.

Special thanks to Bryan Paul, Julio, Brian, Oscar, and Cesar for their professionalism, hard work, and attention to detail. I highly recommend Spencer Home Services for anyone looking for reliable and high-quality service!

Great company, actually stands by their warranty!

Spencer Home Services put in a new main sewer line for me last August. Over the winter, the street patch settled a bit and started turning into a pothole. I called them up to see if they’d fix it under their warranty, and they were awesome about it.

First, they sent someone out two weeks ago to run a camera down the whole pipe. They wanted to make sure the shifting dirt didn't cause any sagging or bellies underground, and they did the inspection with absolutely no pushback or extra fees.

Once we confirmed the pipe was in perfect shape, they scheduled a crew to come back today to fix the road. They cut a clean square and put down a really solid, hot asphalt patch that's completely level with the street.

It's rare to find a company that actually stands by their work and coordinates everything without a fight. Highly recommend them!

I had two projects done at my property. One was reline my sewer line and install a line for a basement half bathroom. The other was replacing my hot water storage tank. The worker quality was excellent, the only problem I had was finding the offices to pay off the work

I had 2 mini split systems installed in my townhome on the second and third floors. The work was done carefully and with good attention to details both outside and inside by Charles Barragan and John Sacharczyk.
They provided thorough instruction with demonstrations on how to operate the systems with a remote regarding all modes, options etc . I am extremely pleased with the service from Spencer Home Service from estimate to completion. Charles and John provided  high quality work and were in a pleasure to work with.

Medford systems & permits

NOAA's 1991-2020 climate normals for Logan Airport (station USW00014739), the nearest NOAA normals station to Medford (about 5 miles southeast), show an annual average of 801.8 cooling degree days and an average summer (June-August) high temperature of 79.6°F.
Medford's Historic District Commission (5 members plus 2 alternates appointed by the Mayor) administers the South Street Historic District; the Commission's own city webpage lists 'Historic District Application Materials' and 'Certificates' among the resources for that district.
Medford's Electrical Department permit fee schedule (in effect since July 28, 2009 and still the fee sheet published on the city's site) prices motor permits -- the category that explicitly includes air conditioners -- at $10 each for fractional-HP units, $20 for 1-5 HP, $30 for 6-10 HP, $40 for 11-25 HP, and a $50 maximum fee per motor.

What summer actually asks of a system in Medford

Medford gets about 63 days above 80°F in a year, and only about 14 above 90°F. That short, concentrated peak is exactly why an oversized air conditioner works badly here: it cools the air quickly, then shuts off before it has pulled the humidity out, leaving the house cold and clammy.
